In an RV the size your looking at it's a matter of personal choice. The larger 35-45' class A's it's a must. There is a higher operating cost to a diesel but you get better performance out of a diesel. By performance I mean pulling power and mpg. New, a diesel is about an $8,000 option on a pickup truck. Diesels tend to last 3-400,000 miles (million miles on a semi) where a gas engines might last 150-200,000 miles and can offer you a higher resale value. If you tow a toad you may find a benefit in a diesel.
My pickup is diesel because I like the pulling power. It's nice to just set the cruise and sit back as I drive through the hills of PA and WV. Diesels also have engine brakes (an option) which are a big help in the mountains. On the other side, the engine is noisier and some people don't like the smell of a diesel. An oil change costs me around $100 vs $30-35 for my car. The diesel engine holds 4 gallons vs 4-6 quarts in a gas engine. I change the oil every 5,000 miles on the diesel (some diesels it's closer to 7,500 miles) and the gas engine is about every 3,000 miles. While diesel parts cost more the largest part of a bill seems to be labor, so I find maintenance in general to be expensive. Diesels also tend to have 2 batteries vs 1 on a gas engine.
My pickup weights 8,000# and I get 17 mpg just driving around and 11 mpg pulling a 12,000# trailer. If I had a gas engine I'd get around 12-14 mpg just driving around and 5-7 mpg towing and I'd be creeping up the hill in the right lane. Instead I go up the hill, not missing a beat with the cruise still set at 60 mph and back down the other side at 60 mph, with the engine brake holding me back and not having to touch the brakes. If I had to stop, I'd have nice cool brakes to stop with.
Good diesel techs are harder to find but so is a good shop mechanic these days. While the local Ford, Chevy, pick a dealer, might not be able to help you there will be a diesel shop that should be able to help you. With the rise in automotive diesels it is getting easier to find a diesel mechanic. I have a local diesel shop that specializes in pickup diesels who does all my work.
Gas vs diesel, it's a tool. Find the right tool for your job.
